spring boot去除get post空格
1.用@ControllerAdvice处理
package com.wangzs.handler;import com.fasterxml.jackson.core.JsonParser;
import com.fasterxml.jackson.databind.DeserializationContext;
import com.fasterxml.jackson.databind.deser.std.StdScalarDeserializer;
import org.springframework.beans.propertyeditors.StringTrimmerEditor;
import org.springframework.boot.autoconfigure.jackson.Jackson2ObjectMapperBuilderCustomizer;
import org.springframework.context.annotation.Bean;
import org.springframework.http.converter.json.Jackson2ObjectMapperBuilder;
import org.springframework.util.StringUtils;
import org.springframework.web.bind.WebDataBinder;
import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.InitBinder;import java.io.IOException;/*** description*/
@ControllerAdvice(basePackages = {"com.wangzs.controller"})
public class GlobalAdvice {/*** 去除get方式的参数空格** @param binder*/@InitBinderpublic void initBinder(WebDataBinder binder) {// 创建 String trim 编辑器// 构造方法中 boolean 参数含义为如果是空白字符串,是否转换为null// 即如果为true,那么 " " 会被转换为 null,否者为 ""StringTrimmerEditor propertyEditor = new StringTrimmerEditor(false);// 为 String 类对象注册编辑器binder.registerCustomEditor(String.class, propertyEditor);}/*** 去除post requestBody实体中的空格** @return*/@Beanpublic Jackson2ObjectMapperBuilderCustomizer jackson2ObjectMapperBuilderCustomizer() {return new Jackson2ObjectMapperBuilderCustomizer() {@Overridepublic void customize(Jackson2ObjectMapperBuilder jacksonObjectMapperBuilder) {jacksonObjectMapperBuilder.deserializerByType(String.class, new StdScalarDeserializer<Object>(String.class) {@Overridepublic String deserialize(JsonParser jsonParser, DeserializationContext ctx)throws IOException {return StringUtils.trimWhitespace(jsonParser.getValueAsString());}});}};}
}
2.测试Controller
package com.wangzs.controller;import lombok.Getter;
import lombok.Setter;
import org.springframework.web.bind.annotation.*;/*** description*/
@RestController
public class StringTrimController {@GetMapping("/get")public String getTest(String id, String name) {return id + "--" + name;}@PostMapping("post")public String postTest(@RequestBody User user) {return user.toString();}static class User {@Setter@Getterprivate String id;@Setter@Getterprivate String name;@Overridepublic String toString() {return "User{" +"id='" + id + '\'' +", name='" + name + '\'' +'}';}}
}
